[wp-hackers] Best practice way for a plugin to use WP_Rewrite

[Tuna Can]

Ok... ignore what I said about not beinag able to write the changes to .htaccess via a them option form submission; that actually works. However, I stand behind the 'admin_init' versus 'init' comment still.

Does the fact that I am using 2.9-rare make a difference?

Thanks,

Tony
